Attached is the latest on my 2006 Toyota Tundra V8. I'm very happy with the results. I did have to add a quart around the 5500 mile mark, but the oil was still full when I changed it after taking this sample. This means I am consuming oil at about 10,000 miles a quart, not bad for 136K miles.
TBN still pretty good. Oil viscosity was just starting to creep up slightly, and the TAN is about 3 points higher than the VOA. I suspect the oil probably could have gone a couple thousand more miles.
Nice, consistent trends of metals. For those of you who follow my UOAs on this vehicle, this UOA is the 24th(!) UOA I have performed on this vehicle. No plans to get rid of it yet.
